All that went unmentioned in public by President Donald Trump when the leaders held talks today in the Philippines.
Reporters saw the beginning of the leaders' bilateral meeting during which Trump praised Duterte's hospitality, the organisation of the summit he was hosting and even Manila's weather.
Trump said nothing about human rights and both leaders ignored shouted questions about the violent drug crackdown. The two men also shared a laugh in the meeting when Duterte called reporters "spies."
Human rights, she added, briefly came up in the context of the Philippines' fight against illegal drugs. She did not say if Trump was critical of the violence.

That appeared to conflict with the Philippines' version of the meeting. Harry Roque, a spokesman for Duterte, said "there was no mention of human rights.
There was no mention of extralegal killings. There was only a rather lengthy discussion of the Philippine war on drugs with President Duterte doing most of the explaining."
He has cozied up to autocrats such as Saudi Arabia's King Salman, Egyptian President Abdel-Fattah el-Sissi and Russian President Vladimir Putin. And earlier in this trip to Asia he made no mention of human rights during multiple appearances in Beijing with Chinese President Xi Jinping.
"Trump seems very comfortable with strongmen. It's not just that he won't criticise Duterte. I wouldn't be surprised if he patted him on the back," said Mike Chinoy, senior fellow at US-China Institute at the University of Southern California, before the meeting.
Government officials estimate that well over 3,000 people, mostly drug users and dealers, have died in the ongoing crackdown. Human rights groups believe the victim total is far higher, perhaps closer to 9,000.
"Human rights groups, I think, will be quite disappointed by the visit," said Amy Searight, director of the Southeast Asia Program at the Center for Strategic and International Studies. "It's unlikely that human rights or rule of law or due process are going to be topics that President Trump will raise."
Late last year, he bragged that he personally pulled the trigger and killed three people years ago while serving as mayor of Davao City. And last week, while in Vietnam for an international summit, he said he took his first life years earlier.
"When I was a teenager, I had been in and out of jail, rumble here and there," Duterte said during a speech in Danang, where he briefly crossed paths with Trump on the sidelines of an international summit. "At the age of 16, I already killed someone."
Trump has shown little interest in pressuring Duterte to rein in the violence, instead saluting him during a May phone call.
"I just wanted to congratulate you because I am hearing of the unbelievable job on the drug problem," Trump told Duterte, according to a transcript of the conversation that later leaked.
"Many countries have the problem, we have a problem, but what a great job you are doing and I just wanted to call and tell you that."
White House officials have suggested there is a strategy behind Trump's flattery of Duterte.
Advisers have said that while Trump was always unlikely to publicly chastise the Philippine president, he may offer criticisms behind closed doors.
Trump would plan to hold his tongue in public in order not to embarrass Duterte, whom he is urging to help pressure North Korea and fight terrorism, and to avoid pushing him into the arms of China.
